You claim that it is observable. How do you know that what you are observing is indeed love? Is it provable?

And, as I stated above, my position is that love does not exist:

So your asserting that love, by this definition: a (1): strong affection for another arising out of kinship or personal ties <maternal love for a child> (2): attraction based on sexual desire : affection and tenderness felt by lovers (3): affection based on admiration, benevolence, or common interests <love for his old schoolmates> b: an assurance of love <give her my love>
